FIG. 1 depicts an exemplary embodiment of a first communication system100 for delivering media content. The communication system 100 canrepresent an Internet Protocol Television (IPTV) broadcast media system.In a typical IPTV infrastructure, there is at least one super head-endoffice server (SHS) which receives national media programs fromsatellite and/or media servers from service providers of multimediabroadcast channels. In the present context, media programs can representaudio content, moving image content such as videos, still image content,and/or combinations thereof. The SHS server forwards IP packetsassociated with the media content to video head-end servers (VHS) via anetwork of aggregation points such as video head-end offices (VHO)according to a common multicast communication method.

The VHS then distributes multimedia broadcast programs via a local areanetwork (LAN) to commercial and/or residential buildings 102 housing agateway 104 (e.g., a residential gateway or RG). The LAN can represent abank of digital subscriber line access multiplexers (DSLAMs) located ina central office or a service area interface that provide broadbandservices over optical links or copper twisted pairs to buildings 102.The gateway 104 distributes broadcast signals to media processors 106such as Set-Top Boxes (STBs) which in turn present broadcast selectionsto media devices 108 such as computers or television sets managed insome instances by a media controller 107 (e.g., an infrared or RF remotecontrol).

The STBs 106 can have built-in digital video recorders (DVRs) or can becoupled an independently operated DVR 105. Unicast traffic can also beexchanged between the media processors 106 and subsystems of the IPTVmedia system for services such as video-on-demand (VoD). It will beappreciated by one of ordinary skill in the art that the media devices108 and/or portable communication devices 116 shown in FIG. 1 can be anintegral part of the media processor 106 and can be communicativelycoupled to the gateway 104. In this particular embodiment, an integraldevice such as described can receive, respond, process and presentmulticast or unicast media content.

The IPTV media system can be coupled to one or more computing devices130 a portion of which can operate as a web server for providing portalservices over an Internet Service Provider (ISP) network 132 to fixedline media devices 108 or portable communication devices 116 by way of awireless access point 117 providing Wireless Fidelity or WiFi services,or cellular communication services (e.g., GSM, CDMA, UMTS, WiMAX, etc.).The computing devices 130 can also include a presence system (hereinreferred to as presence system 130). The presence system 130 can utilizecommon computing and communications technology to monitor subscribercommunication devices operating in communication system 100 (e.g., cellphone, home phone, office phone, home computer, office computer, STB,and so on).

The presence system 130 can for example monitor communication activitiestaking place at the ISP network 132 to determine whether a subscriber ofthe communication system 100 is utilizing an office or home computer.The presence system 130 can also monitor whether the subscriber isutilizing a cellular phone by monitoring the subscriber's location. Forinstance, the presence system 130 can monitor that the cellular phone istransitioning between cellular base stations 117, which can indicate tothe presence system that the subscriber is in transit (traveling in acar, or train). In another illustrative embodiment, or in combination,the presence system 130 can request location coordinates from a cellularphone incorporating a Global Positioning System (GPS) receiver, orutilize triangulation with three or more base stations 117 to hone in onan area where the cellular phone is operating. In another illustrativeembodiment, the presence system 130 can monitor network elements ofcommunication system 100 to detect that the subscriber has downloaded aVoD movie and is presently viewing the movie.

Generally speaking, the presence system 130 can be programmed to monitorthe location and activities of a subscriber of the communication systemby monitoring the use of any of the subscriber's available communicationdevices in communication system 100. Devices in the communication system100 that request from the presence system 130 presence information of asubscriber of the communication system 100 can determine from thisinformation a likely location of the subscriber and likely means tocommunicate with the subscriber.

A satellite broadcast television system can be used in place of the IPTVmedia system. In this embodiment, signals transmitted by a satellite 115can be intercepted by a satellite dish receiver 131 coupled to building102 which conveys media signals to the media processors 106. The mediareceivers 106 can be equipped with a broadband port to the ISP network132. Although not shown, the communication system 100 can also becombined or replaced with analog or digital broadcast distributionssystems such as cable TV systems.

FIG. 2 depicts an exemplary embodiment of a second communication system200 for delivering media content. Communication system 200 can beoverlaid or operably coupled with communication system 100 as anotherrepresentative embodiment of said communication system. The system 200includes a distribution switch/router system 228 at a central office218.

The multicast television stream 230 includes InternetProtocol (IP) data packets addressed to a multicast IP addressassociated with a television channel. The distribution switch/routersystem 228 can cache data associated with each television channelreceived from the intermediate office 220.

The distribution switch/router system 228 also receives unicast datatraffic from the intermediate office 220 via a unicast traffic stream232. The unicast traffic stream 232 includes data packets related todevices located at a particular residence, such as the residence 202.For example, the unicast traffic stream 232 can include data trafficrelated to a digital subscriber line, a telephone line, another dataconnection, or any combination thereof. To illustrate, the unicasttraffic stream 232 can communicate data packets to and from a telephone212 associated with a subscriber at the residence 202. The telephone 212can be a Voice over Internet Protocol (VoIP) telephone. To furtherillustrate, the unicast traffic stream 232 can communicate data packetsto and from a personal computer 210 at the residence 202 via one or moredata routers 208. In an additional illustration, the unicast trafficstream 232 can communicate data packets to and from a set-top boxdevice, such as the set-top box devices 204, 206. The unicast trafficstream 232 can communicate data packets to and from the devices locatedat the residence 202 via one or more residential gateways 214 associatedwith the residence 202.

The distribution switch/router system 228 can send data to one or moreaccess switch/router systems 226. The access switch/router system 226can include or be included within a service area interface 216. In aparticular embodiment, the access switch/router system 226 can include aDSLAM. The access switch/router system 226 can receive data from thedistribution switch/router system 228 via a broadcast television (BTV)stream 222 and a plurality of unicast subscriber traffic streams 224.The BTV stream 222 can be used to communicate video data packetsassociated with a multicast stream.

For example, the BTV stream 222 can include a multicast virtual localarea network (VLAN) connection between the distribution switch/routersystem 228 and the access switch/router system 226. Each of theplurality of subscriber traffic streams 224 can be used to communicatesubscriber specific data packets. For example, the first subscribertraffic stream can communicate data related to a first subscriber, andthe nth subscriber traffic stream can communicate data related to an nthsubscriber. Each subscriber to the system 200 can be associated with arespective subscriber traffic stream 224. The subscriber traffic stream224 can include a subscriber VLAN connection between the distributionswitch/router system 228 and the access switch/router system 226 that isassociated with a particular set-top box device 204, 206, a particularresidence 202, a particular residential gateway 214, another deviceassociated with a subscriber, or any combination thereof.

In an illustrative embodiment, a set-top box device, such as the set-topbox device 204, receives a channel change command from an input device,such as a remoter control device. The channel change command canindicate selection of an IPTV channel. After receiving the channelchange command, the set-top box device 204 generates channel selectiondata that indicates the selection of the IPTV channel The set-top boxdevice 204 can send the channel selection data to the accessswitch/router system 226 via the residential gateway 214. The channelselection data can include an Internet Group Management Protocol (IGMP)Join request. In an illustrative embodiment, the access switch/routersystem 226 can identify whether it is joined to a multicast groupassociated with the requested channel based on information in the IGMPJoin request.

If the access switch/router system 226 is not joined to the multicastgroup associated with the requested channel, the access switch/routersystem 226 can generate a multicast stream request. The multicast streamrequest can be generated by modifying the received channel selectiondata. In an illustrative embodiment, the access switch/router system 226can modify an IGMP Join request to produce a proxy IGMP Join request.The access switch/router system 226 can send the multicast streamrequest to the distribution switch/router system 228 via the BTV stream222. In response to receiving the multicast stream request, thedistribution switch/router system 228 can send a stream associated withthe requested channel to the access switch/router system 226 via the BTVstream 222.

To accomplish a communication session between CDs, an originatingIMS CD 401 can submit a Session Initiation Protocol (SIP INVITE) messageto an originating P-CSCF 404 which communicates with a correspondingoriginating S-CSCF 406. The originating S-CSCF 406 can submit the SIPINVITE message to an application server (AS) such as reference 410 thatcan provide a variety of services to IMS subscribers. For example, theapplication server 410 can be used to perform originating treatmentfunctions on the calling party number received by the originating S-CSCF406 in the SIP INVITE message.

Originating treatment functions can include determining whether thecalling party number has international calling services, and/or isrequesting special telephony features (e.g., *72 forward calls, *73cancel call forwarding, *67 for caller ID blocking, and so on).Additionally, the originating S-CSCF 406 can submit queries to the ENUMsystem 430 to translate an E.164 telephone number to a SIP UniformResource Identifier (URI) if the targeted communication device is IMScompliant. If the targeted communication device is a PSTN device, theENUM system 430 will respond with an unsuccessful address resolution andthe S-CSCF 406 will forward the call to the MGCF 420 via a BreakoutGateway Control Function (BGCF) 419.

When the ENUM server 430 returns a SIP URI, the SIP URI is used by anInterrogating CSCF (I-CSCF) 407 to submit a query to the HSS 440 toidentify a terminating S-CSCF 414 associated with a terminating IMS CDsuch as reference 402. Once identified, the I-CSCF 407 can submit theSIP INVITE to the terminating S-CSCF 414 which can call on anapplication server 411 similar to reference 410 to perform theoriginating treatment telephony functions described earlier. Theterminating S-CSCF 414 can then identify a terminating P-CSCF 416associated with the terminating CD 402. The P-CSCF 416 then signals theCD 402 to establish communications. The aforementioned process issymmetrical. Accordingly, the terms “originating” and “terminating” inFIG. 4 can be interchanged.

IMS network 450 can also be operably coupled to the presence system 130previously discussed for FIG. 1. In this representative embodiment, thepresence system 130 can be accessed over a PSTN or VoIP channel ofcommunication system 400 by common techniques such as described above.

FIG. 5 depicts an exemplary embodiment 500 of a portal 530. The portal530 can be used for managing services of communication systems 100-400.The portal 530 can be accessed by a Uniform Resource Locator (URL) witha common Internet browser such as Microsoft's Internet Explorer using anInternet-capable communication device such as references 108, 116, or210 of FIGS. 1-2. The portal 530 can be configured to access a mediaprocessor such as references 106, 204, 206, 316, and 324 of FIGS. 1-3and services managed thereby such as a Digital Video Recorder (DVR), anElectronic Programming Guide (EPG), VoD catalog, a personal catalogstored in the STB (e.g., personal videos, pictures, audio recordings,etc.), and so on.

FIG. 6 depicts an exemplary method 600 operating in portions ofcommunication systems 100-400. Method 600 begins with step 602 in whicha DVR which can be an integral component of an STB or an independentlyoperated device coupled to the STB (see FIG. 1) is programmed by a userwith a recording schedule of desired video content from any one of anumber of media channels supplied by the media communications systems ofFIGS. 1-4. In addition to the recording schedule, the user of the DVRcan program the DVR in step 604 with a memory utilization threshold.Suppose for example that the DVR has a memory capacity of 200 hours ofvideo recordings. The user can set a threshold of 198 hours. That is,the DVR can monitor when recordings have reached or exceeded thisthreshold. Alternatively, or in combination, the threshold can bedefined in memory capacity terms (e.g., Megabytes or Gigabytes).

Once these settings have been established, the DVR proceeds to step 606where it records video content as directed by the recording scheduleestablished in step 602. In step 608, the DVR determines whether videocontent recordings have reached or exceeded the threshold set in step604. If the threshold has not been reached, the DVR continues recordingvideo content in step 606 according to the recording schedule. If thethreshold is reached, the DVR proceeds to step 610 where it generates anotice that describes the state of one or more resources in the DVR. Thestate of resources can include for example how much memory capacity isavailable for recording video content (in hours of recording time,Megabytes, Gigabytes, etc.), a description of a portion of the recordingschedule (such as a description of media programs that have recordingtimes near the time when the threshold was exceeded), a description ofwhich recordings will require mitigation of memory resources, and/or adescription of media files that are stored in the DVR (e.g., a directoryof media files with descriptive filenames such as program names,episodes, etc.).

In step 612, the DVR can be programmed to identify a communicationidentifier of a communication device. The communication identifier canrepresent an E.164 telephone number or SIP URI as described earlier. Thecommunication device can represent a fixed-line telephone, mobile phonesuch as a cellular phone, or computing device such as a desktop orlaptop computer. In step 614, the DVR can transmit the notice to thecommunication device, which in turn can present it to its user in step616. The notice can be transmitted over a wireline medium, wirelessmedium, or combinations thereof. The notice can be transported in anyformat such as, for example, an email message, a short message servicemessage (also commonly referred to as an SMS message), or a multimediamessage service message (also commonly referred to as an MMS message),just to mention a few.

In step 616, the communication device can present the user withresources statistics of the DVR (e.g., memory utilization at 98%, 100multimedia files stored, there is enough memory for a 1 hour recording,and so on). The communication device can also present a portion of therecording schedule where one or more conflicts may arise if room is notmade available in the memory resource such as the hard drive and/orFlash memory of the DVR. Additionally, the communication device can beprogrammed to present a description of multimedia files stored in theDVR. All of this information can be retrieved by the communicationdevice from the notice supplied by the DVR.

From this presentation, a user of the communication device can choose tomitigate the potential memory conflict by selecting multimedia files todelete, or transfer to another device such as the STB coupled to theDVR, a storage device located in the premises where the DVR is situatedor in a remote location accessible by the DVR. Alternatively, or incombination, the user of the communication device can choose to modifythe DVR recording schedule to mitigate the memory conflict.

The user can choose any of the above mitigation options by common meansthrough a user interface of the communication device (e.g., display,keypad, and navigation functions) to generate in step 618 a number ofinstructions for the DVR which are transmitted to the DVR in step 620over a wireline or wireless medium as described earlier. Upon receivingthese instructions in step 622, the DVR can begin to manage its memoryresources accordingly. For instance, the instructions may requiretransfer or deletion of media files to increase memory space.Additionally, or in the alternative, the instructions may requirechanging the recording schedule in a manner that reduces memory usageby, for example, removing one or more program recordings from theschedule.

Upon reviewing the aforementioned embodiments, it would be evident to anartisan with ordinary skill in the art that said embodiments can bemodified, reduced, or enhanced without departing from the scope andspirit of the claims described below. For example, method 600 can beadapted to apply steps 624-626. In step 624 the DVR can be programmed toretrieve presence information of the user of the DVR from the presencesystem 130. The presence information can indicate to the DVR which of anumber of communication devices available to the user is being used bythe user, or is accessible to the user at the time the threshold wasexceeded. In some instances, the presence information may indicate morethan communication device can be targeted to access the user (e.g., cellphone and/or computer terminal). In such circumstances, the DVD can beprogrammed in step 626 to select more than one communication device ofthe user to convey the notice. Once the selection is made, the DVR canbe programmed to identify corresponding communication identifier(s) instep 612 of the selected communication device(s). The communicationidentifiers can be stored in the DVD, or retrieved by the DVD from aremote network element (e.g., a subscriber account management system)operating in any one of the media communication systems of FIGS. 1-4.

In step 628, the DVR can be programmed to determine one or moremitigation options which can be included in the notice generated in step610. The DVR can, for example, collectively analyze the recordingschedule, memory utilization, and the multimedia files in storage at thetime the threshold was exceeded. From this analysis, the DVR canidentify media files that have not been used for an extended period oftime by the user of the DVR (e.g., more than a week), and identify theunused multimedia files as candidates for deletion or transfer to aback-up storage system. The DVR can also identify one or more mediaprograms in the recording schedule which are periodically recorded, butare frequently not being viewed by the user. These mitigation optionscan be transmitted with the notice, which the user can accept, reject orignore once presented at the communication device.

Broadly speaking, method 600 can be adapted to operate in a mediarecording device that records video and/or audio content distributed onone or more media channels (e.g., IPTV, satellite TV, cable TV, Internetradio programs, streaming music programs, etc.). Method 600 can beadapted so that the media recorder can be programmed with a mediarecording schedule (audio and/or video content), and a threshold foridentifying an excess use of memory resources. When the threshold isexceeded, the media recorder can notify its user according to any of theembodiments previously described to prevent exhausting the mediarecorder's resources.

Other suitable modifications can be applied to the present disclosurewithout departing from the scope of the claims below. Accordingly, thereader is directed to the claims section for a fuller understanding ofthe breadth and scope of the present disclosure.
